Title:
COILING MACHINE STRUCTURE CAPABLE OF ACCURATELY CONTROLLING REEL TORQUE AND REEL TORQUE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/088405
Kind Code:
A1
Abstract:
A coiling machine structure capable of accurately controlling the reel torque, comprising a rack (1), a reel (2), magnetorheological fluid clutches (3), a speed reducer (4), a motor (5) and a torque synthesis speed reducer (6). The reel is rotatably arranged on the rack, the speed reducer is transmittingly connected to the motor, and the speed reducer is transmittingly connected to the reel by means of the plurality of magnetorheological fluid clutches and the torque synthesis speed reducer. Also provided is a torque control method for the coiling machine capable of accurately controlling the reel torque. In a transmission chain of a driving reel in a traditional coiling machine, a magnetorheological fluid clutch is additionally arranged in series, and accurate control over the torque of the driving reel is achieved by accurately controlling the working torque of the magnetorheological fluid clutch, so that the tension output from the reel working torque to a metal strip foil is accurately controlled, the tension control precision of metal strip foil rolling production is greatly improved, and a good device foundation is laid for the technical level improvement of the metal rolling production industry and the rolling production of the precision metal strip foil.
